. Referring now to the aforesaid illustrativel embodiment ofthe presentinvention, and

withparticu'lar reference to the'v drawings illustrating the same, l0 inFig. l of thedrawyings indicates a tubular member from which thetubulari'segments constituting the' links of theaforesaid illustrativeembodiment of .the present invention may vreadily be cut.

The t'ubularmember 10 may be of any desired precious metal, althougliitmay bemade of any `desired `material- Its lbore may likelike ofsuiciient strength to serve satisfactorily its purpose o fhingedlyconnecting suc- Y 'ce'ssve tubular segments made in the manner Referringtothedrawings, in which we less diagrammatically eKempl1- now to bedescribed.

making the Vtubular segments Ain Vaccordance with the principles of thevpresent stated'that the tubular member 10 may, be-

fore being cutinto the segments 20 more Vclearlyillustrated in Fig. 2 ofthe drawings,

.be givena slightfcurvature of the jig o r die which.holdslthetubularmember l0 for the cutting or severing-operation. Accordingly, ifthetubular member 1Q is initially round or is forced into such a slightcurvilinear form, each ofthel tubular segments 20-will have a slightcurvilinear form; The purpose of this isto predispose the members 20assembled in the final braceletillustrated in '"Figy is a plan `view ofa series or succession of tubularA segments and associated hinge Fig. 6of 'thedrawings towards a curvature around the? wrist which the finalbracelet is member-S120 will naturally .assume agcurvilinear vpositionaround the wrist of the wearer the cuts 11 are V-shaped. It may Vhere bea member which may be in the form Of im" oblong or elongated membergenerally designated by reference character 30,`the cross dimension ofwhich is preferably of such size as to enable the piece 30 toiit snuglyinto the tubular link members 20. As 4 clearly shclwn in Fig. 4 ci thedrawings, thc member 30 may be soldered along its edges 32 and 33 vtothe inner wall of the tubular member 2O so as to be securely and rigidlyheld therein at its end. The other end 35 of the post 30 is intended. tcbc hingedly secured by a suitable pin or rivet 4() which will passthrough the Opening 36 in the hinge post 30.

As shown in F ig. 5 of the drawings, where we have shown an assemblageof tubular link members and their associated posts, the hinge post 30rigidly connected to one of the tubular link members 20, is hingedlyconnected t0 the succeeding hinge member Q0 by the pin or A rivet 40which passes through and issoldered cr otherwise ixcclly secured in theadjacent end of the adjoining tubular link member 20 'and is freelyrotatable in the opening 36 at the other end of the hinge post 30, Itis, of

course, to be clearly understood that the angle of tolerance or Qfmovement; of the tubular link members 2O with respect to each other islimited by the V-.shapedcut at ODG end and the i/-shaped projeCtiQIl atthe other end of each of the tubular link members 2Q. 1t is also to berecalled that due to the slight curvature which is preferably given'eachof the: tubular link members 20, the assembled articulated structure isbiased towards a curvature aroundthe wrist or other member to which thestructure is to be applied and against a Vcurvature in the oppositedirection. The tubular link members, assembled in the manner shown inFigs. 4 and 5 of the" A drawings, may be assembled in the form of thecomplete bracelet shown in Fig. 6 of the drawings where the bracelet hasbeen generally designated by reference character and the watch which itholds by the reference character GO. It will be noted that the bracelet50 is made up of twu link structures 5l and 52, each being of thearticulated construction described in v`detail above, on one side of theconnecting member 5,3 and of two` other such articulated link structures`54: and 55 on the other side of the connecting member 53, 5G indicatingthe means. for ccmicctng A the bracelet 50 to one side 0f the watch 60 YThe device possesses the necessary mechaniand 57 indicating the meansfor connecting the bracelet 50 to the other side of the watch 60.

This completes the description of the aforesaid illustrative embodimentof the present .m

invention. Itfwill be noted that the construction is simple and thedevices made in accordance therewith may be readily and economicallyfabricated and, assembled.

cal strength and flexibility in use and is furthermcrc very neat andattractive in appearance.

'Other supe'rioritics and advantages of the devices of the resentinvention, particularly as exemplifiedJ in the aforesaidT illustrativeembodiment of the same, will readily occur to those skilled in the artto Which the 'present invention relates. i

It may here be stated that the tubularfgf;

sections may be straight instead of curved and that they may be made inhalf or other fractional tubular sections instead of from unitarytubular sections. It may here further be stated thatinstead of solderingonepgo end of each pin o r hinge post Within one of the tubularsections, the hinge posts may be attached by swaging or other suitablemetal working operation.

It may here also be stated that the original'74A `#95 tubular memberfrom which the tubular link segments are cut may initially be straightbut Vthat the tubular link segments may themselves be given a slightcurvilinear conformation by being placed in a curvilinearl jig dur-C 10cing the operation of attaching the hinge osts, 'i f What we claim as ourinvention is: l, An articulated structure of the general characterspecified, comprising a plurality 01""105 hingedly associated links eachcomprising a substantially tubular member having a substantiallyV-shaped conformation at one of its ends.l

2, An articulated structure of the general" character specified,comprising a plurality of hingedly associated links each comprising alsubstantially tubular member havinga substantially V-shapedconformation at each of its ends. l 3. An articulated structure `ofthe-general character specified, comprising a plurality of hingedlyassociated links, each link comprising a tubular member having asubstantially,

V-shaped conformation at each of its ends, l

the Vs at the ends ofsaid links being substantially parallel te reachother, and a series 0f hinged pests one end of each ci whchs fixedlysecured and the other end of each of which is hingedly secured in the.correspcnding end cf the adjacent link..

4. All articulated structure. of thegeneral character specied, comrising a plurality of hingedly associated linli) s each comprising asubstantially tubular member having a subwhich is ixedly secured and theother end ofeach of Which is hingedly secured in the corresponding endof the adjacent link, each of said tubular bodies being slightly curvedalong a substantially circular arc in substantially the same directionand to substantially the same degree.

In testimony whereof, We have signed our names to this specicat-ion this3rd day of March, 1930.
